I really appreciate your reply, Dawn, and understand that I should be fine, since I don't owe any taxes. In fact, I'm due for refunds from both Federal & State.
I'm just concerned that TT has made such an error, and wonder what other errors it has made for who know how many others. Their subroutine is calculating this line incorrectly.
Of course, it also bothers me, that form 4868 makes it look like I owe money (although, if anyone looks at it, they'll see that line 6 was generated wrong), but that's nothing, compared to how this might affect others.
